My dog hasn't been eating anything for the last week almost and we've tried to give him everything, even French toast because he loves it, but he won't eat anything. He only drinks water and then he goes outside and pukes. He also doesn't spend any time with us anymore and is trying to separate from us. The vet thinks he might have pancreatic cancer. We think he is going to starve before the results even come back. Can anyone answer this for me please?
